WebMay 27, 2014 · Upgrading biogas refers to the increase of methane concentration in product gas by removal of CO2, which increases its heating power. Several treatment technologies are available for biogas upgrading: high pressure water scrubbing (HPWS), pressure swing adsorption, membrane separation, chemical absorption, and gas permeation. WebJul 1, 2005 · This perhaps is the simplest method for scrubbing biogas. Bhattacharya et al. [4] developed one such water scrubbing system. The process provides 100% pure methane but is dependent on factors like dimensions of scrubbing tower, gas pressure, composition of raw biogas, water flow rates and purity of water used.
